Can I use a US Samsung Note 4 in Korea? Voltage difference cause problem?

hello all.
i bought a samsung galaxy note 4 mobile in US. may i use the same mobile in korea with the charger from korea (220V). i jus tried few times. now the mobile is getting heated up and battery is draining fast. whether it is reason because of voltage difference ?
kindly help me.

The charger input (look at the label) should be something like 100-240 Volts, so that will work. The phone may not, it depends on the frequencies used by the phone and by your Korean carrier (and whether the phone is SIM-unlocked).
